2 Claims. (01. 240108) be quickly and easily assembled and machinesewed.

Another object is to provide a lamp shade which eliminates the necessityof covering the wire frame with tape or cloth before applying the liningand cover thereto.

A further object is to treat and prepare the edges of a relativelydelicate lamp shade material with a moisture impervious tape which iscoated on one side with a thermoplastic adhesive,

so that the cover and lining will not be affected by oxidation of themetal frame.

These and other objects of the invention will become apparent from areading of thefollowing specification and claims, together with theaccompanying drawing, in which like parts are referred to and indicatedby like reference characters and wherein:

Figure 1 is a perspective view of a conventional lamp shadeembodyingthis invention, with parts broken away to show construction;

Figure 2 is a plan view of either the lining or cover member of suchshade;

Figure 3 is an enlarged side view of a portion of the shade, showing itsconstruction;

Figure 4 is a vertical cross-sectional view of a portion of the lampshade frame and lining during the first stage of construction;

Figure 5 is a view of the same elements during the second stage of itsconstruction;

Figure 6 is a view showing certain parts during the third stage ofconstruction;

Figure 7 is a view showing the fourth stage of construction;

Figure 8 is a view showing the fifth stage of construction; and

Figure 9 is a similar view of the aforementioned elements finallyassembled on a completed lamp shade.

Referring to the drawing, there is shown a metal lamp frame II, a clothlining 2|, a cloth cover 3|, and a trim member 4 I. These members willbe described in detail and in the order just set forth.

The bottom ring H and the top ring |2 of the shade are spaced apart andare held together by means of the ribs or strut-like members 13 whichare welded or otherwise securely fastened thereto. The spider M whichconsists of a small hub-like member having a plurality of arms extendingradially therefrom is attached to the upper ring I2 and is used formounting the shade on the lamp base. While the lamp shade is illustratedin its simplest and most popular form, nevertheless it is to beunderstood that the lower and upper rings H and I2 and the ribs l3 maybe formed and assembled to make lamp shades of many different styles andshapes.

The lining 2| is a piece of textile fabric sewed together at its lateraledges 24 to form a tubular or conical section. Its width is slightlygreater than that of the finished lamp shade and its lower and upperedges are caused to fold outward and around the frame rings II and I2.The lining 2| is drawn and mounted rather tightly and conceals thestruts I3 from the inside.

The tape member 22 is applied to the upper and lower marginal edges ofthe lining 2| and is applied before the edges 24 are sewed together.This tape or ribbon 22 is made of a waterproof textile fabric that has athermoplastic adhesive applied to one surface thereof. This tape isattached or bonded to the upper and lower edges of the lining 2|, asindicated in the Figure 2, by the application of heat and pressure. Ihave found that a moisture repellent material that is now being used inthe construction of mens hats and which is placed between the leatherperspiration band and the crown is ideally suited for this purpose, whenone side is coated with a thermoplastic adhesive of the type that is nowused on mending tape. The tape 22 stiffens the marginal edges of thelining 2| and enables it to be machine sewed around the ring members Thelining member 2| is attached as shown in the Figures 4 and 5 with thetape member 22 immediately surrounding the metal frame. The machinestitches 23, passing through both the lining and the tape, are placed asclose to the ring members I and I2 as possible and form a tightwaterproof pocket for the frame element. The constricted or top edge ofthe lining 2| is then attached to the top ring l2 in a similar manner.However, it is cut or slit laterally to accommodate the spider M whereit is fastened to the top ring.

' The cover member 3| is substantially the same as the lining member 2|;that is, it is slightly wider than the lamp shade is high and itslateral edges 34 are sewed together to make a cylindrical or conicalelement. It is placed over the frame to conceal the ribs Hi from theoutside. The lower edge of the cover and the moisture repellent tapemember 32 which is similarly applied to the margin thereof bythermoplastic adhesive are folded inward and cover the heretoforedescribed folded edge of the lining member 2|, as is clearly shown inthe Figure 6 of the drawing. A series of machine stitches 33 is applieda short distance above the aforementioned stitches 23, as is indicatedin the Figure 7. The metal frame ring II is then encased or enclosed intwo layers of waterproof material, one layer of the lining material, andone layer of the cover mate-- rial. The top taped marginal edge isapplied to the heretofore described cover SI and ring l2 in the samemanner.

The trim member 4| is a bias-cut textile fabric that has some degree ofelasticity. One longitudinal edge thereof is provided with a hem Q3. Theother edge thereof is sewed to the lining and cover members 2| and 3|and to one layer of the waterproof material 32 on the inside of theshade, as shown by stitches 42 in the Figure 8. The trim member 4| isthen turned downward andoutward and around the wire frame I i and theheretofore described lining and cover members so that the hem 43 facesinward. The elasticity of the trim member keeps it in place as is shownin the Figure 9 and all of the stitches and edges are entirely concealedfrom either inside or outsideview;

It should lie-understood that the tape 32 may be dispensed with if thefabric of the cover ft is strong enough to warrant direct application.In that event, the ring will be coveredwith one ply of moistureimpervious tape; one ply of the lining,. one: ply" of: the cover and:one ply of the finishing'tape.

Having thus disclosed the invention in its preferred form, it should beunderstood that the description and illustration thereof are not to beconstrued in a limited sense as there maybe other forms or modificationsof the invention which may also be considered to come within the scopeof the appended claims.

I claim:

1. A lamp shade, comprising, a. frame member, a first sheet memberhaving a marginal portion, a, first moisture-impervious tape memberbonded to the marginal portion folded in one direction around andsecured to a portion of the frame, a second sheet member having amarginal portion and a second moisture-impervious tape member bonded tothe second marginal portion folded in the opposite direction around andsecured to a portion of the frame and the first sheet member.

2. In a-lamp shade of the type having a metal frame the combination of alining and a cover, comprising a first sheet member having a marginalportion, a first tape member bonded to the marginal portion, both ofsaid first members being folded in one direction around and attached toa-portion of the aforesaid frame, a second sheet member having amarginal portion, and a second tape member bonded to the second marginalportion, both of said second members being folded in the oppositedirection around and attached to a portion of the aforesaid frame andthe said first sheet and tape members, both of the aforesaid tapemembers being a moisture impervious, waterproof textile fabric.
